Since 07/2018 statement 2 number appear on my bill ********** 895 and ********** 802 as I understand this was activated in 05/2016 but I was never billed for such number. Your customer care can not assist and wants me to register *****. I am not going to register ***** it is your job to investigate and tell me how this numbers suddenly appear on my bill in 07/2018. your customer care dept. do not want to make the effort in investigating as to why this happend. Just want to pass the bucket. I want this money refunded and a cancellation form which your cancellation department do not want to send it to my personal assistant when she asked for it. I was hanging on for a long time yesterday 23/10 after I have spoken to your customer care dept. I want this matter sort out asap and want these no of my account. I am very busy and my personal assistant will handle any enquiries. Carike Prinsloo
